Donpaul.p's Possible Experimentation

i think i might just set up some cfls and give it a try, here is the exact info relating to 21.36-12
[DISCLAIMER]: This information is provided as experimental data and not fact.

The only photoperiod manipulation from years of experiments that offered discernible improvements was this adjustment made for 1 or 2 calendar weeks at the point of maximum flowering rate: Daylength of 21 hours, 36 minutes with a dark period of 12 hours. To accomplish this, you need a 7 day, 24 hour digital timer. During a 7 day calendar week on Earth, the "sun" only cycles 5 times. This permits easily switching back to the regular 12/12 at your discretion. You may want to only alter during peak flower production to stimulate the plant's metabolism. Using this photoperiod throughout the flowering cycle will cause this:

A variety that takes 49 days of 12/12 to mature, won't see 49 - 12 hour dark periods under 21:36/12 until almost 10 calendar weeks have passed.

The total increase in light energy is almost 80%, which will produce larger yields, if all of your other enviromental conditions are kept optimal.

The total increase in flowering period is only 40%, half the potential room for improvement. This means you don't have to be perfect to win out.

Selective application of the 21:36/12 photperiod for only 1 or 2 weeks extends the wait only 2 to 4 Earth days, which makes up the missing 2 complete day and night cycles each week on Planet Ito. This permits the additional light energy to be provided without purchasing additional equipment or overloading existing circuits, which maximizes the existing system's capabilities. The main advantage is that matched with co2 and optimal nutrition, the plants metabolism will increase dramatically. I have only successfully tested this photoperiod for two weeks. The potential for a net increase of 40% over the entire cycle (80% increase in light energy vs. 40% longer wait) is worthwhile. Don't be afraid!

Day 1 - Sunday, 6:00am til Monday, 3:36am
Day 2 - Monday, 3:36pm til Tuesday, 1:12pm
Day 3 - Wednesday, 1:12am til Wednesday, 10:48pm
Day 4 - Thursday, 10:48am til Friday 8:24am
Day 5 - Friday, 8:24pm til Saturday 6:00pm

..

now im not willing to give that schedule a try just yet, its obviously easy to set up with a 7 day timer so thats not the issue, but id prefer to go with something like 14-12 or even 16-12,

its the dark period thats important here as the 12 hours of dark is the part that lets the flowering hormones to build up, but does it need to be 12 hours ever 12 hours or can it be pushed further, ill set up a cfl flower room at the start of my next round of flowering plants and ill give 14-12 a try,

21.36-12 seems a bit harsh to me.


ok now i got some new seeds to add to my grow program and not sure which to go and plant, my flower room is about half way through so i can plant a few more seeds, ive all ready got some growing
dragons breath
jack flash
the new white widow x skunk thats not released yet but free samples from herbies
kc45 auto
my own fem seeds x2,
so thats what ive got growing in seedlings stage at the minute,
now i want to plant an auto and 2 regular seeds.
so heres the list
00 seeds auto northern lights x1 fem
female seeds auto bubble x 1 fem
female seeds big grapefruit x1 fem
nirvana blue mystic regular x2
nirvana ice regular x2
sativa blackberry regular x2
big buddha cheese fem x1, suppose to be true uk cheese
now the free seeds i got are
delicious cotton candy fem x1
samsara green love potion fem x2
more white widow x skunk#1 x5 regular seeds (got 2 in seedlings stage so far)

so theirs my choices, i want an auto and 2 none autos, so big budda will be one of the none autos so as anyone grown any of these in the list and if so was it a good strain to grow,
